1) At a certain position, the temperature on the 300 hPa chart is -48°C; according to the tropopause chart, the tropopause is at FL 330. What is the most likely temperature at FL 350?
300 hPa corresponds to FL300 approx
Temp at FL300 = -48 Deg C
Temp at FL330 = -48 Deg C + (2(30-33)) Std ISA Lapse Rate = -54 Deg C
Tropopause begins at FL330. thus, temperature at FL350 =
-54 Deg C
